摘要：

对布置有涡发生器小翼对的圆管内部湍流流动和强化传热特性进行了三维数值模拟。研究了涡发生器的形状和对数对流动传热特性的影响并采用综合性能指标进行优化。结果表明：涡发生器后横截面上产生的多纵向涡结构使管内流体混合更加充分，促进了壁面边界层与主流的动量和能量交换，提高了传热强度。每排4对矩形小翼时的换热性能最好，Nusselt数比光管平均提高了27.2%。相同形状下，每排4对涡发生器的综合性能均高于每排3对；相同对数下，梯形小翼的综合性能最好，三角形小翼次之，矩形小翼最差。每排4对梯形小翼时的整体综合性能最优，性能评价标准达到了0.97～1.07。

Abstract:

Various technologies on heat transfer enhancement have been exploited to develop more efficient compact heat exchanging devices. In this research, turbulent heat transfer and flow characteristics in a circular tube, with longitudinal vortex generators (LVG) on the wall, were numerically investigated. The effects of LVG shapes and number of pairs on Nusselt number, friction factor and performance evaluation criteria were numerically studied. The results showed that pairs of longitudinal vortexes were generated behind the LVG, which enhanced the fluid mixing in the tube, and promoted the momentum and energy exchange between the wall boundary layer and the main flow. Further analysis indicated that the tube with 4 pairs of rectangular winglets on each row held the best heat transfer performance, and the Nusselt number was improved by 27.2% compared with smooth tube on average. The tube with 4 pairs of trapezoidal winglets on each row presented the best performance evaluation criteria, and the value reached 0.97 — 1.07.

Key words: heat transfer, flow, turbulent flow, vortex generator, longitudinal vortex
